Audioscenic Amphi High-Dimensional Sound with BeClear Technology Licensed from Philips

Audioscenic announced a technology collaboration with Philips and NXP Semiconductors to demonstrate the world’s first reference design for gaming soundbars. This breakthrough combines Audioscenic Amphi Hi-D spatial audio featuring AI position sensing with Acoustic Echo Cancellation (AEC) from Philips BeClear. Product designers, product managers, and engineers can experience the reference design in person at Computex Taipei 2025.
 

Gamers have long faced a trade-off: enjoy rich, immersive sound through speakers or have clear voice communication with teammates through headsets. While headsets have dominated hardcore gaming, many players prefer speaker systems like soundbars for extended comfort without headset fatigue, and a more natural “room-filling” audio experience versus the inside-your-head sound of headsets.

Powered by the NXP i.MX 8M Mini applications processor, this new Audioscenic solution enables soundbar manufacturers to deliver fully immersive, location-accurate game audio simultaneously with crystal-clear voice chat — a combination previously unachievable in gaming soundbars.

Underneath the sleek design of audio devices that feature both speakers and microphones is a series of complex technologies that work in concert. The core technology enabling this breakthrough is Acoustic Echo Cancellation (AEC). For multiplayer voice chat to work during gameplay, the sound of the game needs to be blocked or cancelled while voice chat is transmitted through microphone arrays. Without this cancellation, other gamers on the chat would hear a jumbled mix of voice and game audio layered on top of their own game audio, resulting in unintelligible communication.

What makes this reference design truly revolutionary is how it handles Audioscenic’s position-adaptive audio technology. Powered by AI position sensing, Amphi Hi-D dynamically delivers consistent 3D audio across multiple speakers as gamers naturally move in their gaming space — no more sweet spots or fixed listening positions. This adaptivity presents a unique challenge for conventional AEC systems, which typically struggle with moving sound sources. The Philips BeClear solution is specially tuned to maintain voice clarity regardless of how the Hi-D system redistributes game audio based on player movement.

The technical demands of this system require significant processing power. With Philips BeClear AEC game audio reproduced through Hi-D, the solution cancels all the audio through an instantaneous convergence process before it feeds back to the microphones. The NXP i.MX 8M Mini applications processor with Quad Arm Cortex-A53 running at 1.8GHz per core and 8-channel PDM audio input delivers the computational power needed to process both the 3D sound positioning and real-time echo cancellation simultaneously.

 

“This collaboration perfectly showcases the capabilities of our i.MX 8M family of SoCs,” says Mario Centeno, General Manager, IoT Edge, at NXP Semiconductors. “The i.MX 8M Mini delivers the power and speed needed to simultaneously process this first-to-market combination of Audioscenic’s AI-driven spatial audio and Philips BeClear AEC in a compact soundbar.”

“Now is the time for the game voice chat experience to advance, and Audioscenic is proud to work in partnership with global tech leaders Philips and NXP on this innovative Hi-D proof-of-concept,” adds Marcos Simon, CTO and Co-Founder of Audioscenic. “Philips BeClear running on the NXP chipset with position-adaptive multichannel Hi-D sound unpacks the cluster of game audio and voice, providing remarkable immersive sound and voice clarity without the disruption of noise and echoes.”

The Amphi Hi-D gaming soundbar reference design is part of the demonstrations promoted by Audioscenic at Computex 2025 (May 19-23).
